Yes, trading off latency to save bandwidth is definitely an incorrect
approach. Bandwidth will keep increasing much faster than latency
decreases (and there are hard physical limits to decreasing latency, while
bandwidth could go up to infinity).
On high-latency high-bandwidth connections (satellite, 3G/4G) it may
already be cheaper to download all versions of all images than to wait for
CSS to be able to select the right ones to load. Solution that requires
page layout for image loading is a step backwards for performance.
